PLANING MACHINE.

Application filed April 28, 1923, Serial No.

This invention relates to planing, shaping and like machines and has for its object-t0 provide a machine of this type which will afford greater rigidity between the tool and the bed than is ordinarily obtainable and which, while applicable to any purpose for which it may be suited, will be particularly adapted for cutting slots in the rotors of turbo-altcrnators.

To this end, the invention consists in a planing, shaping or like machine wherein the usual cross and vertical slides are replaced by one or more transversely adjustable side columns carrying one or more vertically adjustable tool holders or clapper boxes. A preferred construction comprises two oppositely-disposed side columns, each carrying two oppositely-disposed clapper boxes.

In order that the invention may be clearly understood and readily carried into practice, reference will now be made to the accompanying drawings wherein a planing machine constructed in accordance therewith is illustrated by way of example; Figure 1 being a plan, and Fig. 2 an end elevation.

In the form illustrated, the planing machine comprises a base 3 supporting a slidable table 4 and provided with centrally and oppositely-disposed transverse slide rests 5.

Adjustably mounted oneach slide rest 5 is a relatively massive column 6 or 6, provided with vertical slide rests 7 or 7 carrying oppositely-disposedindependently'adjustable clapper boxes 8 or 8.

The columns and clapper boxes may be variously constructed, two preferred forms being illustrated in the drawings. In the form illustrated at the left-hand side of both figures, the column 6 iscast withthe slide rests 7 disposed side by side parallel with the table 4 and each clapper box 8 comprises a slide 9 with a tool support 10 and top and bottom cheeks 11 cast integral therewith, the clapper 12 being pivotally connected with and supported by the tool support 10 in the usual manner. In the form illustrated at the righthand side of both figures, the column 6' is cast with the slide rests 7 on opposite sides 7 635,228, and in Great Britain May 1; 1922.

of a Wedge-like portion 13 and each clapper box comprises a slide 9 with a rim 14 extending around three sides thereof, the clapper'12 being in this case pivotally connected with and supported by the slide 9. In both the forms illustrated, each slide 9 and 9 has an independent vertical adjustment indicated by the screws 15. It will be understood, of course, that either of the columns illustrated with its appropriate clapper boxes may be provided at each side of thetable, different constructions being illustrated in a single machine merely as a matter of convenience.

It will also be understood that any suitable automatic or other mechanism may be provided for feeding the columns 6 and 6 to and from the work and for adjusting the clapper boxes 8 and 8. Means may also be provided in connection with the feed mechanism for the side columns 6 and-6 for looking the latter, after each inward travel or feed increment'has been applied to the same.

We claim as our invention 1. A planing machine or the like comprising two oppositely-disposed transversely adj ustable side columns each carrying two separate oppositely-disposed and individually adjustable tool holders.

2. A planing machine or the like comprising a support, a work-carrying bed movably mounted thereon, a plurality of side columns extending transversely of said bed, transversely movable saddles mounted on said columns and a pair of oppositely disposed individually adjustable tool holders pivotally mounted on the respective saddles.

3. A planing machine or the like comprising a support, a work-carrying bed movably mounted thereon, a plurality of side columns extending transversely of said bed, transversely movable saddles mounted on said columns and a pair of oppositely-disposed and vertically adjustable tool holders pivotally mounted on the respective saddles.

4. A planing machine or the like comprising a support or work-carrying bed movably mounted thereon, a side column extending" transversely of said bed and having a projecting central portion, and a plurality of portion, and a pair of vertically adjustable 10 tool-holders mounted on the respective sides tool-holders mounted on the respective of said central portion. saddles.

5. A planing machine or the like compris- In testimony whereof, we have hereunto 5 ing a support or Work-carrying bed movably' subscribed our names this sixteenth day of mounted thereon, a side column extending April, 1923. transversely of said bed and having a Wedgelike inner portion, a pair of movable saddles WALTER SYMES. mounted on opposite sides of said Wedge-like REGINALD GAYTER-
